No. 16/130,004, filed on Sep. 13, 2018, entitled “COGNITIVE OPTICAL CONTROL SYSTEM AND METHODS,” and Canadian Patent Application No. 2,980,396, filed on Sep. 27, 2017, entitled “COGNITIVE OPTICAL CONTROL SYSTEM AND METHODS,” all of which are incorporated herein by reference in their entirety.

FIELD

Generally, the present disclosure technically relates to medical imaging systems. More particularly, the present disclosure technically relates to control of optical systems for medical imaging systems. Even more particularly, the present disclosure technically relates to smart control of optical systems for medical imaging systems.

BACKGROUND

In the related art of surgery, imaging and imaging guidance is becoming a more significant component of clinical care, such as relating to disease diagnosis, disease monitoring, surgical approach planning, facilitating guidance during the procedure, and facilitating post-operative follow-up, or being a component of a multi-faceted treatment approach. Some related art systems involve integration of imaging data in a surgical suite for neurosurgery, wherein brain tumors are typically excised through an open craniotomy approach that is guided by a related art imaging device. The related art imaging device typically uses data from computerized tomography (CT) scans with an associated contrast (iodinated contrast) feature and magnetic resonance imaging (MRI) scans with associated contrast (gadolinium contrast). These related art systems involve registering the imaging data sets together, translating a three-dimensional imaging space to a three-dimensional space of a patient, tracking instruments relative to the patient, and the associating imaging data by way of an external hardware system, such as a mechanical arm, a radio-frequency device, or an optical tracking device. These related art systems have experienced many challenges. For instance, related art tissue visualization in operating rooms is frequently hindered by many factors outside control of an optical chain. Specifically, external factors, such as tissue composition and ambient lighting, negatively affect the ability of a user to differentiate various types of tissues within a visualized area of a surgical site. Therefore, a need exists for a smart optical control system and methods to overcome many of the related art challenges.

Unless defined otherwise, all technical and scientific terms used herein are intended to have the same meaning as commonly understood by one of ordinary skill in the art. Unless otherwise indicated, such as through context, as used herein, the following terms are intended to have the following meanings:

As used herein, the phrase “access port” refers to a cannula, conduit, sheath, port, tube, or other structure that is insertable into a subject, in order to provide access to internal tissue, organs, or other biological substances. In some embodiments, an access port may directly expose internal tissue, for example, via an opening or aperture at a distal end thereof, and/or via an opening or aperture at an intermediate location along a length thereof. In other embodiments, an access port may provide indirect access, via one or more surfaces that are transparent, or partially transparent, to one or more forms of energy or radiation, such as, but not limited to, electromagnetic waves and acoustic waves.

As used herein the phrase “intraoperative” refers to an action, process, method, event or step that occurs or is carried out during at least a portion of a medical procedure. Intraoperative, as defined herein, is not limited to surgical procedures, and may refer to other types of medical procedures, such as diagnostic and therapeutic procedures.

Referring to FIG. 1 , this diagram illustrates, in a side view, the insertion of an access port into a human brain, for providing access to internal brain tissue during a medical procedure, in accordance with an embodiment of the present invention. An access port 12 is inserted into a human brain 10, providing access to internal brain tissue. The access port 12 may include such instruments as catheters, surgical probes, or cylindrical ports, such as the NICO® BrainPath®. Surgical tools and instruments may then be inserted within the lumen of the access port in order to perform surgical, diagnostic, or therapeutic procedures, such as resecting tumors, as necessary. The present disclosure applies equally well to catheters, deep brain stimulation (DBS) needles, a biopsy procedure, and also to biopsies and/or catheters in other medical procedures performed on other parts of the body. In the example of a port-based surgery, a straight or linear access port 12 is typically guided down a sulcal path of the brain. Surgical instruments would then be inserted down the access port 12.

Referring to FIG. 2 , this diagram illustrates, in a perspective view, a navigation system environment 200, wherein an exemplary medical navigation system 205 for supporting minimally invasive access port-based surgery is implemented, in accordance with an embodiment of the present disclosure. The exemplary navigation system environment 200 may be used to support navigated image-guided surgery. A surgeon 201 conducts a surgery on a patient 202 in an operating room (OR) environment. A medical navigation system 205 comprising an equipment tower (not shown), a tracking system 321 (FIG. 3 ), displays 311 and tracked instruments 360 assist the surgeon 201 during his procedure. An operator 203 is also present to operate, control, and assist the medical navigation system 205. The tracked instruments 360 may be calibrated by way of the calibration and methods as presently disclosed.

Referring to FIG. 3 , this block diagram illustrates a control and processing system 300 operable in the medical navigation system 200, e.g., as part of the equipment tower, in accordance with an embodiment of the present disclosure. In one example, control and processing system 300 may include one or more processors 302, a memory 304, a system bus 306, one or more input/output interfaces 308, a communications interface 310, and storage device 312. Control and processing system 300 may be interfaced with other external devices, such as tracking system 321, data storage 342, and external user input and output devices 344, which may include, for example, one or more of a display, keyboard, mouse, sensors attached to medical equipment, foot pedal, and microphone and speaker. Data storage 342 may be any suitable data storage device, such as a local or remote computing device, e.g. a computer, hard drive, digital media device, or server, having a database stored thereon. In the example shown in FIG. 3 , data storage device 342 includes identification data 350 for identifying one or more medical instruments 360 and configuration data 352 that associates customized configuration parameters with one or more medical instruments 360. Data storage device 342 may also include preoperative image data 354 and/or medical procedure planning data 356. Although data storage device 342 is shown as a single device in FIG. 3 , understood is that in other embodiments, data storage device 342 may be provided as multiple storage devices.

Still referring to FIG. 3 , the medical instruments 360 are identifiable by control and processing unit 300. The medical instruments 360 may be connected to and controlled by control and processing unit 300, or medical instruments 360 may be operated or otherwise employed independent of control and processing unit 300. Tracking system 321 may be employed to track one or more of medical instruments 360 and spatially register the one or more tracked medical instruments to an intraoperative reference frame. For example, medical instruments 360 may include tracking spheres that may be recognizable by a tracking camera 307 and/or tracking system 321. In one example, the tracking camera 307 may be an infrared (IR) tracking camera. In another example, a sheath placed over a medical instrument 360 may be connected to and controlled by control and processing unit 300.

Still referring to FIG. 3 , the control and processing unit 300 may also interface with a number of configurable devices, and may intraoperatively reconfigure one or more of such devices based on configuration parameters obtained from configuration data 352. Examples of devices 320, as shown in FIG. 3 , include one or more external imaging devices 322, one or more illumination devices 324, a robotic arm 305, one or more cameras 307, one or more projection devices 328, and one or more displays 311.

Still referring to FIG. 3 , exemplary aspects of the disclosure can be implemented via processor(s) 302 and/or memory 304. For example, the functionalities described herein can be partially implemented via hardware logic in processor 302 and partially using the instructions stored in memory 304, as one or more processing modules or engines 370. Example processing modules include, but are not limited to, a user interface engine 372, a tracking module 374, a motor controller 376, an image processing engine 378, an image registration engine 380, a procedure planning engine 382, a navigation engine 384, and a context analysis module 386. While the example processing modules are shown separately in FIG. 3 , in one example the processing modules 370 may be stored in the memory 304 and the processing modules may be collectively referred to as processing modules 370.

Still referring to FIG. 3 , understood is that the system is not intended to be limited to the components shown. One or more components of the control and processing system 300 may be provided as an external component or device. In one example, navigation module 384 may be provided as an external navigation system that is integrated with control and processing system 300.

Still referring to FIG. 3 , some embodiments may be implemented using processor 302 without additional instructions stored in memory 304. Some embodiments may be implemented using the instructions stored in memory 304 for execution by one or more general purpose microprocessors. Thus, the disclosure is not limited to a specific configuration of hardware and/or software.

Still referring to FIG. 3 , while some embodiments can be implemented in fully functioning computers and computer systems, various embodiments are capable of being distributed as a computing product in a variety of forms and are capable of being applied regardless of the particular type of machine or computer readable media used to actually effect the distribution.

Still referring to FIG. 3 , at least some aspects disclosed can be embodied, at least in part, in software. That is, the techniques may be carried out in a computer system or other data processing system in response to its processor, such as a microprocessor, executing sequences of instructions contained in a memory, such as read only memory (ROM), volatile random access memory (RAM), non-volatile memory, cache or a remote storage device.

Still referring to FIG. 3 , a computer readable storage medium can be used to store software and data which, when executed by a data processing system, causes the system to perform various methods. The executable software and data may be stored in various places including for example ROM, volatile RAM, non-volatile memory and/or cache. Portions of this software and/or data may be stored in any one of these storage devices.

Still referring to FIG. 3 , examples of computer-readable storage media include, but are not limited to, recordable and non-recordable type media such as volatile and non-volatile memory devices, ROM, RAM, flash memory devices, floppy and other removable disks, magnetic disk storage media, optical storage media (e.g., compact discs (CDs), digital versatile disks (DVDs), etc.), among others. The instructions may be embodied in digital and analog communication links for electrical, optical, acoustical or other forms of propagated signals, such as carrier waves, infrared signals, digital signals, and the like. The storage medium may be the internet cloud, or a computer readable storage medium such as a disc.

Still referring to FIG. 3 , at least some of the methods described herein are capable of being distributed in a computer program product comprising a computer readable medium that bears computer usable instructions for execution by one or more processors, to perform aspects of the methods described. The medium may be provided in various forms such as, but not limited to, one or more diskettes, compact disks, tapes, chips, USB keys, external hard drives, wire-line transmissions, satellite transmissions, internet transmissions or downloads, magnetic and electronic storage media, digital and analog signals, and the like. The computer useable instructions may also be in various forms, including compiled and non-compiled code.

Still referring to FIG. 3 , according to one aspect of the present application, one purpose of the navigation system 205 (FIG. 2 ), which may include control and processing unit 300, is to provide tools to the neurosurgeon that will lead to the most informed, least damaging neurosurgical operations. In addition to removal of brain tumours and intracranial hemorrhages (ICH), the navigation system 205 can also be applied to a brain biopsy, a functional/deep-brain stimulation, a catheter/shunt placement procedure, open craniotomies, endonasal/skull-based/ENT, spine procedures, and other parts of the body such as breast biopsies, liver biopsies, etc. While several examples have been provided, aspects of the present disclosure may be applied to any suitable medical procedure.

Referring to FIG. 4A, this flow diagram illustrates a method 400 of performing a port-based surgical procedure by way of using a navigation system, such as the medical navigation system 205, as described in relation to FIG. 2 , in accordance with an embodiment of the present disclosure. At a first block 402, the port-based surgical plan is imported. Once the plan has been imported into the navigation system at the block 402, the patient is affixed into position using a body holding mechanism 404. The head position is also confirmed with the patient plan in the navigation system, as indicated by block 404, which in one example may be implemented by the computer or controller forming part of the equipment tower (not shown). Next, registration of the patient is initiated, as indicated by block 406. The phrase “registration” or “image registration” refers to the process of transforming different sets of data into one coordinate system. Data may include multiple photographs, data from different sensors, times, depths, or viewpoints. The process of “registration” is used in the present application for medical imaging in which images from different imaging modalities are co-registered. Registration is used in order to be able to compare or integrate the data obtained from these different modalities.

Still referring to FIG. 4A, appreciated is that the present disclosure encompasses numerous registration techniques and at least one of the techniques may be applied to the present example. Non-limiting examples include intensity-based methods that compare intensity patterns in images via correlation metrics, while feature-based methods find correspondence between image features such as points, lines, and contours. Image registration methods may also be classified according to the transformation models used to relate the target image space to the reference image space. Another classification can be made between single-modality and multi-modality methods. Single-modality methods typically register images in the same modality acquired by the same scanner or sensor type, for example, a series of magnetic resonance (MR) images may be co-registered, while multi-modality registration methods are used to register images acquired by different scanner or sensor types, for example in magnetic resonance imaging (MRI) and positron emission tomography (PET). In the present disclosure, multi-modality registration methods may be used in medical imaging of the head and/or brain as images of a subject are frequently obtained from different scanners. Examples include registration of brain computerized tomography (CT)/MRI images or PET/CT images for tumor localization, registration of contrast-enhanced CT images against non-contrast-enhanced CT images, and registration of ultrasound and CT.

Referring to FIG. 4B, this flow chart illustrates the step of registering a patient for a surgical procedure, as indicated by block 406, in the method 400 of using the navigation system, as shown in FIG. 4A, in greater detail, in accordance with an embodiment of the present disclosure. If the use of fiducial touch points 440 is contemplated, the method involves first identifying fiducial markers on images, as indicated by block 442, then touching the touch points with a tracked instrument, as indicated by block 444. Next, the navigation system computes the registration to reference markers, as indicated by block 446. Of course, the medical navigation system 205 has to know the relationship of the tip of tracked instrument relative to the tracking markers of the tracked instrument with a high degree of accuracy for the blocks 444 and 446 to provide useful and reliable information to the medical navigation system 205. An example tracked instrument is discussed below with reference to FIG. 5 and a calibration apparatus for verifying and establishing this relationship is discussed below in connection with FIGS. 6-8 .

Still referring to FIG. 4B, alternately, registration can also be completed by conducting a surface scan procedure, as indicated by block 450. The block 450 is presented to show an alternative approach, but may not typically be used when using a fiducial pointer. First, the face is scanned using a 3D scanner, as indicated by block 452. Next, the face surface is extracted from MR/CT data, as indicated by block 454. Finally, surfaces are matched to determine registration data points, as indicated by block 456. Upon completion of either the fiducial touch points 440 or surface scan 450 procedures, the data extracted is computed and used to confirm registration at block 408, shown in FIG. 4A.

Still referring to FIG. 4B and referring back to FIG. 4A, once registration is confirmed, as indicated by block 408, the patient is draped, as indicated by block 410. Typically, draping involves covering the patient and surrounding areas with a sterile barrier to create and maintain a sterile field during the surgical procedure. The purpose of draping is to eliminate the passage of microorganisms, e.g., bacteria, between non-sterile and sterile areas. At this point, conventional navigation systems require that the non-sterile patient reference is replaced with a sterile patient reference of identical geometry location and orientation. Numerous mechanical methods may be used to minimize the displacement of the new sterile patient reference relative to the non-sterile one that was used for registration but it is inevitable that some error will exist. This error directly translates into registration error between the surgical field and pre-surgical images. In fact, the further away points of interest are from the patient reference, the worse the error will be.

Still referring to FIG. 4B and referring back to FIG. 4A, upon completion of draping, as indicated by block 410, the patient engagement points are confirmed, as indicated by block 412, and then the craniotomy is prepared and planned, as indicated by block 414. Upon completion of the preparation and planning of the craniotomy, as indicated by block 414, the craniotomy is cut and a bone flap is temporarily removed from the skull to access the brain, as indicated by block 416. Registration data is updated with the navigation system at this point, as indicated by block 422. Next, the engagement within craniotomy and the motion range are confirmed, as indicated by block 418. Next, the procedure advances to cutting the dura at the engagement points and identifying the sulcus, as indicated by block 420.

Still referring to FIG. 4B and referring back to FIG. 4A, thereafter, the cannulation process is initiated via the trajectory plan, as indicated by block 424. Cannulation involves inserting a port into the brain, typically along a sulci path as identified at 420, along a trajectory plan. Cannulation is typically an iterative process that involves repeating the steps of aligning the port on engagement and setting the planned trajectory, as indicated by block 432, and then cannulating to the target depth, as indicated by block 434, until the complete trajectory plan is executed, as indicated by block 424.

Still referring to FIG. 4B and referring back to FIG. 4A, once cannulation is complete, the surgeon then performs resection, as indicated by block 426, to remove part of the brain and/or tumor of interest. The surgeon then decannulates, as indicated by block 428, by removing the port and any tracking instruments from the brain. Finally, the surgeon closes the dura and completes the craniotomy, as indicated by block 430. Some aspects, shown in FIG. 4A, are specific to port-based surgery, such as portions indicated by blocks 428, 420, and 434, but the appropriate portions of these steps may be skipped or suitably modified when performing non-port based surgery.

Still referring to FIG. 4B and referring back to FIG. 4A, when performing a surgical procedure using a medical navigation system 205, the medical navigation system 205 must acquire and maintain a reference of the location of the tools in use as well as the patient in three dimensional (3D) space. In other words, during a navigated neurosurgery, there needs to be a tracked reference frame that is fixed relative to the patient's skull. During the registration phase of a navigated neurosurgery, as indicated by block 406, a transformation is calculated that maps the frame of reference of preoperative MRI or CT imagery to the physical space of the surgery, specifically the patient's head. This may be accomplished by the navigation system 205 tracking locations of markers fixed to the patient's head, relative to the static patient reference frame. The patient reference frame is typically rigidly attached to the head fixation device, such as a Mayfield clamp. Registration is typically performed before the sterile field has been established, as indicated by block 410.

Referring to FIG. 5 , this diagram illustrates, in a perspective view, an implementation of a cognitive optical system S (FIGS. 6-8 ) for dynamically refining imaging during a medical procedure, in this example, neurosurgery. As shown, the area indicated by the dotted lines is designated as a region-of-interest ROI, wherein the processor 10 (FIG. 6 ) of the system S (FIG. 6 ) is configured to fine tune an optical change in relation to parameters, such as color, saturation, brightness, contrast, and the like. The processor 10 is configured to recognize an ROI by way of a medical tool, such as a pointer tool, wherein an enhanced image is displayed corresponding to the area indicated by the pointer tool.

Referring to FIG. 6 , this schematic diagram illustrates a cognitive optical system S for dynamically refining imaging during a medical procedure, in accordance with an embodiment of the present disclosure. The system S generally comprises: a processor 10 operable by a set of executable instructions storable in relation to a non-transitory memory device (not shown) and configured to automatically adjust an image by: automatically compensating for at least one external factor affecting an anatomical area being viewed; automatically adjusting at least one imaging parameter; and automatically adjusting at least one internal control of an optical chain, whereby a quality of the image is improvable in real time.

Still referring to FIG. 6 , the system S further comprises at least one of a camera device or system 20, an optics device or system 30, an illumination device or system 40, a display device or system 50, a preoperative input device 60, an intraoperative input device 70, at least one external navigation device or system 80 and at least one advanced optical or spectroscopic device or system 90, in accordance with embodiments of the present disclosure. The intraoperative input device 70 is configured to receive input from at least one external navigation device or system 80 and at least one advanced optical or spectroscopic device or system 90. Each of the processor 10, the camera device 20, the optics device 30, an illumination device 40, and a display device 50 is configured to receive input from the preoperative input device 60 as well as to receive input from, and transmit output to, the intraoperative input device 70.

Still referring to FIG. 6 , in the system S, the optical chain comprises at least one of component of optics, mechanical hardware, electronic hardware, firmware, and software. The at least one imaging parameter comprises at least one of illumination, saturation, color, contrast, and opacity. The processor 10 is configured to at least one of: automatically adjust illumination by adjusting at least one of an illumination spectrum and a luminance in relation to the camera device 20, such as a camera scope, automatically adjust color by adjusting color filters in relation to the camera device 20, such as the camera scope, automatically adjust saturation by processing the image to reduce light, and automatically adjust opacity by at least one of adjusting an infrared illumination level and applying a filter. The processor 10 is configured to automatically adjust an image based on at least one input parameter comprising at least one of a host tissue type, a pathology type, an environmental condition, an optical chain variable, and a plurality of user experience data, such as via the preoperative input device 60.

Still referring to FIG. 6 , in the system S, the processor 10 utilizes a machine learning technique, and/or any other artificial intelligence technique, to automatically adjust the image based on the at least one input parameter by fine tuning the optical chain. The processor 10 is configured to learn from data relating to sources, such as informatics, pathological information, past surgical information, and the like, for facilitating and/or accelerating the medical procedure, such as neurosurgery. By using the machine learning technique, the processor 10 is configured to learn without being explicitly programmed and its functions are not limited by the set of executable instructions. The processor 10 is configured to learn from, and make predictions based on, data, such as past data and real-time data, thereby making data-driven predictions, or determinations, e.g., via building a model from sample inputs, and thereby overcoming strict adherence to the set of executable instructions. Machine learning is employed by the processor 10 in a range of operations, wherein an explicit set of executable instructions for a given operation is infeasible, e.g., in relation to computer vision or imaging.

Still referring to FIG. 6 , in the system S, the processor 10 utilizes a machine learning technique, involving computational statistics, which also focuses in prediction-making, e.g., involving mathematical optimization. The machine learning technique may also comprise data mining techniques, involving an exploratory data analysis or an unsupervised learning technique. The machine learning technique may also involve learning and establishing baseline behavioral profiles for various entities or subjects, e.g., patients, and then use the baseline behavioral profiles to find meaningful anomalies. The exploratory data analytics facilitates developing complex models and updatable instructions for prediction, e.g., via predictive analytics. These analytical models allow the processor 10 to provide medical professionals, such as surgeons, with reliable and repeatable decisions and to develop insights through learning from historical relationships and data trends. The machine learning technique comprises at least one technique of: decision tree learning, association rule learning, deep learning, inductive logic programming, support vector machines, clustering, Bayesian networks, reinforcement learning, representation learning, similarity and metric learning, sparse dictionary learning, Genetic algorithms, rule-based machine learning, and learning classifier.

Still referring to FIG. 6 , in the system S, the set of executable instructions comprises a predictive macro-optimization instruction based on a multi-modal real-time tissue interrogation for facilitating dynamically refining imaging. The predictive macro-optimization instruction comprises informatics, whereby the processor 10 is configured to determine at least one ideal condition corresponding to the at least one external factor. The processor 10 is configured to instruct an imaging device or system, such as the camera device 20, to provide a prompt requesting approval of an automated adjustment of the at least one imaging parameter prior to rendering an adjusted image on the display device 50.

Still referring to FIG. 6 , in the system S, the informatics comprises a feature for learning information relating to previous procedures. The information relating to previous procedures comprises at least one type of imaging parameter for optimizing tissue differentiation. The at least one internal control of the optical chain comprises at least one of a zoom level, a numerical aperture, a camera type, an exposure time, an exposure gain, a de-noising strength, a local area contrast enhancement strength, a display type, a brightness level, and contrast level.

Still referring to FIG. 6 , the cognitive optical system S generally improves image quality by automatically adjusting internal controls of the optical chain (hardware, firmware, and software) to compensate for external factors that affect an area of a surgical site being viewed, whereby a surgeon's ability to view anatomy is improvable, in accordance with some embodiments of the present disclosure. For example, ambient conditions in the environment surrounding tissue at a surgical site may cause increased illumination, thereby saturating the tissue being imaged, e.g., when a headlamp is being used. Such additional illumination is adjustable by way of the cognitive optical system S by adjusting the illumination spectrum and luminance output by the camera device 20, e.g., the camera scope, by adjusting colour filters in the camera scope, and/or by processing the image to reduce the presence of such light. In another example, the cognitive optical system S is implementable if blood is saturating a field of view (FoV) at a surgical site, e.g., automatically detecting whether excess blood is present and adjusting, e.g., automatically adjusting infrared illumination level to reduce opaqueness of the excess blood. Alternatively, the cognitive optical system S uses a filter to reduce the opaqueness.

Still referring to FIG. 6 , such adjustments to the optical chain are dynamically performed by the cognitive optical system S; and, in some embodiments, such adjustments to the optical chain are performed in real-time, whereby visualization of the tissue of interest is constantly being re-enhanced. Also, noteworthy is that at least the following factors are considered by the cognitive optical system S as adjustable inputs: type of host tissue, type of pathology, ambient and local environmental conditions, optical chain variables, information relating to a plurality of user experiences (or transactions), wherein a predictive macro optimization comprising a dynamic refinement is provided based on multi-modal real-time tissue interrogation.

Still referring to FIG. 6 , the cognitive optical system S, comprising the processor 10, is implementable in the context of informatics, wherein the processor 10 learns the ideal conditions relating to a set of specific external factors. For example, glioblastomas or “gliomas” (GBMs) have been imaged, e.g., by way of an imaging system, wherein the ideal lighting conditions to best view these gliomas have been determined. The cognitive optical system S is implementable with the imaging system to verify whether tissue at a given surgical site has a GBM at any time an external measurement is taken of an imaged area. In another example, if a Raman signal indicates that a given portion of tissue indicates at least one of a tumor or a necrotic tissue section, the cognitive optical system S is configured to automatically alter the spectrum of light to maximize differentiability between healthy and unhealthy tissue (such as the tumor or necrotic tissue section) by rendering a boundary more visible therebetween than hitherto possible by using related art optical systems.

Still referring to FIG. 6 , the cognitive optical system S involves an adjustment of parameters, such as incident lighting, via the illumination device 40. However, in implementing some embodiments of the present disclosure, wherein factors, such as tissue composition, are not adjustable, the processor 10 is configured to adjust a plurality of optical parameters, e.g., for use by the optics device 30, to render at least one optimized image on the display device 50, wherein the at least one optimized image comprises at least one of a “true” image of the tissue (as seen by a true source, such as at least one of a naked eye and a spectroscopic image of viewed tissue), and an enhanced image for facilitating optimized tissue differentiation, whereby surgical performance is improvable.

Still referring to FIG. 6 , noteworthy is that any automated adjustment of imaging parameters should be approved by a surgeon, such as by way of a prompt from the optical system S prior to rendering the at least one optimized image on the display device 50. The optical system S is configured to learn information from previous procedures, such as the types of imaging parameters that are likely to provide an image which facilitates the best or optimized tissue differentiation. For example, if the tissue of interest is preoperatively known by the system S as a glioma, the processor 10 is configured to adjust at least one imaging parameter to acquire an image, whereby imaging of the glioma is optimized. In another example, the processor 10 is configured to consider outcomes of previous procedures and to determine what imaging parameters influence better or optimized imaging outcomes. In yet another example, the processor 10 of the system S is configured to consider and/or analyze a plurality of “glioma” images taken, e.g., by way of an imaging system, whereby analyzed information is provided, and to cross-correlate such analyzed information with a set of optical parameters resulting in the best or optimized imaging, e.g., by way of an imaging system. The processor 10 of the system S uses the set of optical parameters, resulting in the best or optimized imaging, to adjust at least one imaging parameter of the optical chain in relation to a given pathology, e.g., a glioma.

Still referring to FIG. 6 , when searching for brain tumors, the processor 10 of the system S is configured to enhance colour contrast in at least one of the highlights and the mid-tones of an acquired image. In other embodiments, the processor 10 of the system S is configured to adjust other available parameters in relation to a given type of surgery. In some embodiments, the processor 10 of the system S is configured to use a hierarchal structure for performing any dynamic parameter adjustment. The use of a hierarchical structure is important in the system S for at least that, in some surgical cases, optimizing one part of the optical chain, after a different optimization has already been achieved, may otherwise cause a situation wherein optimization of one parameter results in a degradation of another parameter.

In executing the method M2, illumination should be set as high as is comfortable to a user, considering a distance for which illumination is increasable without harming the patient. In executing the method M2, the cognitive optical system S considers various parameters in the optical chain, such as a zoom level and a numerical aperture in relation to the optical system 30, an exposure time, an exposure gain and de-noising strength, and a local area contrast enhancement strength in relation to the camera system 20, as well as brightness and contrast in relation to the display device 50.

The system S considers, not only the optical chain, but payload information, robotic arm information, and monitor information as well. The processor 10 receives input from the preoperative input device 60 and the intraoperative input device 70, wherein the intraoperative input device 70 receives input from at least one component, such as the navigation devices or external devices 80 and advanced optical or spectroscopic devices 90.

Still referring back to FIGS. 1-8 , the processor 10 is further configured to determine whether an image is representative of the actual volume of view (VoV), e.g., by using image variables, such as tissue type, e.g., brain tissue, liver tissue, etc., and pathological type, by using factors that are intrinsic to an image, in comparison with factors that are related to the optical chain and with environmental factors, wherein an image can be automatically adjusted with an option of being manually overridden if necessary.

Still referring back to FIGS. 1-8 , in a red environment, e.g., a blood environment, the processor 10 is further configured to provide instructions for prompting irrigating the red environment with water, wherein determining whether irrigation is necessary comprises using a photometer). In a surgical procedure, a major challenge in image processing relates to tissue heterogeneity (not all parts of a given tissue appear the same). To address at least this challenge, the processor 10 is further configured to provide instructions for displaying a dashboard of suggested actions, e.g., Siri for operation, for obtaining inputs from multi-modal sources, for providing output to effect optical chain video adjustment, for initially tuning all parameters, whereby further image processing is effected only as a last resort, thereby minimizing the degree of “untruth” in an image. Specifically, in a blood environment, the processor 10 is further configured to provide instructions for monitoring inputs from all other components, whereby the system S acts as an imaging “watchdog.”
